Ciara or Missy Elliot I'd assume. Missy produced this second monster hit for her. Ain't any on par her who are in the US big leagues, IMO. It's a pretty sparse "song" that focusses on dance rather than melody. Here's a project - try to find a melody in the charts - period. If you do, I'm betting it's a tried-and-true cover version.
Sound has utterly displaced music in the industry - good stuff!
